covers-validator

PHPUnit @covers tags validator

Why?

PHPUnit fails to generate a coverage report when tests have invalid @covers tags.

This tool allows you to determine the tests that have invalid @covers tags without you needing to run the coverage.

Usually coverage reports are run less often than the tests as they take a long time to run. This tool validates your @covers tags quicker than you run your tests.

Trying to @cover or @use not existing class or interface "NonExistentClass".
Trying to @cover or @use not existing method "ExistingClass::nonExistantMethod".
